Product details
Overview
ICE1PCS01HKLA1 from Infineon Technologies is an 8-pin Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC for boost-topology AC-DC front-ends, supporting universal input (85–265 VAC), programmable switching frequency (50–250 kHz), average current control, and integrated protections including brown-out, peak current limiting, and output under-voltage detection. It delivers precise 5 V ±2% internal reference and 95% max duty cycle at 125 kHz for Class D-compliant industrial power supplies.
For engineers reviewing the ICE1PCS01HKLA1 datasheet, ICE1PCS01HKLA1 pinout, ICE1PCS01HKLA1 application, or ICE1PCS01HKLA1 equivalent, this controller is selected for high-efficiency, low-harmonic PFC stages in server PSUs, LED drivers, and industrial SMPS where stable bus voltage regulation, fast load-step response, and external loop compensation flexibility are required.
Technical Context
The ICE1PCS01HKLA1 implements a dual-loop cascaded control architecture: an inner average current loop (using ISENSE and ICOMP pins) shapes sinusoidal input current, while an outer voltage loop (via VSENSE and VCOMP) regulates 380–400 V DC bus voltage. Its variable oscillator sets frequency via resistor on FREQ pin, and nonlinear gain block enables harmonic suppression across line cycles.
Protection logic includes cycle-by-cycle peak current limiting (triggered at ISENSE > 1.1 V), brown-out detection (VSENSE < 0.8 V), open-loop protection, and soft over-current control. The GATE driver delivers 1.5 A sink/source with 11.5 V clamp, enabling direct drive of CoolMOS™ PFC switches without external buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology Support | Boost converter only; requires external MOSFET and diode; not compatible with flyback or interleaved PFC. |
| Input Voltage Range | 85–265 VAC universal line; validated per IEC 61000-3-2 Class D harmonic limits. |
| Switching Frequency | 50–250 kHz programmable via resistor to ground on FREQ pin; enables EMI optimization and choke size reduction. |
| Reference Voltage | 5.0 V ±2% trimmed internal reference at VSENSE; ensures accurate 380–400 V bus regulation tolerance. |
| Duty Cycle Limit | 95% typical maximum at 125 kHz; prevents MOSFET shoot-through and sustains CCM operation up to full load. |
| GATE Drive Capability | 1.5 A source/sink with 11.5 V clamp; directly drives 10 nC gate charge MOSFETs at 200 kHz without buffer stage. |
| Soft-Start Current | 10.8 µA constant current into VCOMP; linearly ramps input current to limit inrush stress on boost diode. |
Pinout & Package
ICE1PCS01HKLA1 is housed in PG-DIP-8 package (dual-in-line plastic, 0.3 inch width), with through-hole mounting and creepage/clearance compliant for 300 V RMS working voltage. Pin 1 is GND (top-left corner, notch-marked side).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | IC Ground Reference | Common return for all analog and power sections; must be low-inductance connection to power ground plane. |
| 2 ICOMP | Current Loop Compensation Node | Integrates OTA2 output to stabilize inner current loop; connects external RC network for phase margin tuning. |
| 3 ISENSE | Current Sense Input | Accepts voltage drop across external shunt (R1); triggers peak current limit at >1.1 V; requires series R2 (220 Ω) for inrush protection. |
| 4 FREQ | Frequency Setting Input | Resistor-to-ground sets oscillator frequency; 100 kΩ yields ~125 kHz; tolerance directly impacts PFC efficiency and EMI profile. |
| 5 VCOMP | Voltage Loop Compensation & Soft-Start | Hosts RC network for outer loop stability; 10.8 µA soft-start current ramps VCOMP to control startup current slew rate. |
| 6 VSENSE | Output Bus Voltage Feedback | Senses scaled VOUT via resistive divider; comparator trips at 0.8 V (brown-out) or 4.75–5.25 V (OVP/UVLO thresholds). |
| 7 VCC | IC Supply Input | 10–21 V DC auxiliary supply; UVLO activates at 11.2 V turn-on / 10.2 V shutdown; no internal clamp - external Zener required. |
| 8 GATE | MOSFET Gate Driver Output | Drives PFC switch gate; 1.5 A drive strength supports ≤10 nC gate charge; 11.5 V clamp protects gate oxide. |
Key Features
| Feature | Design Value |
|---|---|
| Average Current Control Architecture | Enables near-unity PF (>0.99) and low THD (<5%) across full line/load range without digital computation. |
| External Loop Compensation | Independent ICOMP and VCOMP pins allow full customization of current/voltage loop bandwidth and phase margin. |
| Enhanced Dynamic Response | Fast recovery from 50% load steps in <20 ms due to adaptive OTA1 gain shift after soft-start completion. |
| Class D Harmonic Compliance | Fulfills IEC 61000-3-2 Class D requirements for equipment with input power ≤600 W without additional filtering. |
| Integrated Protection Suite | Five independent protections (BOP, OVP, UVP, OCL, OLP) reduce BOM count and improve system reliability vs discrete solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCM PFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2PCS01G | Successor with integrated 650 V start-up cell, lower quiescent current (120 µA), and extended frequency range (30–300 kHz). | Eliminates need for external auxiliary supply; suitable for cost-sensitive consumer PSUs but lacks ICE1PCS01HKLA1's 1.5 A gate drive strength. | Select ICE2PCS01G when auxiliary supply integration reduces BOM cost and board space is constrained. |
| UCC28070 | Two-phase interleaved CCM controller with internal PWM modulator; requires external op-amps for loop compensation. | Supports >1 kW PFC with reduced ripple and thermal stress; incompatible with single-phase boost due to fixed interleaving logic. | Select UCC28070 only for systems requiring >1 kW output or strict ripple reduction; not drop-in replaceable. |
Compared with ICE2PCS01G and UCC28070, ICE1PCS01HKLA1 offers higher gate drive capability and simpler single-phase implementation, making it optimal for 300–800 W industrial PSUs where robustness and external loop tuning outweigh integration benefits.

FAQ
What is the recommended external sense resistor value for ISENSE on ICE1PCS01HKLA1?
The ISENSE pin triggers peak current limiting at 1.1 V. For a 10 A peak input current, use R1 = 1.1 V / 10 A = 0.11 Ω (1206 package, 1% tolerance, 2 W rating). A 220 Ω series resistor (R2) is mandatory between the shunt and ISENSE to limit inrush current into the pin during startup.
Does ICE1PCS01HKLA1 support discontinuous conduction mode (DCM)?
No - ICE1PCS01HKLA1 is explicitly designed for continuous conduction mode (CCM) operation. Under light loads, the system may naturally enter DCM due to inductor characteristics, but the IC does not regulate or optimize for DCM; its average current control loop assumes CCM waveform integrity.
Can VCC be powered directly from the rectified AC line?
No - VCC requires a regulated 10–21 V DC auxiliary supply. Direct connection to rectified line violates absolute maximum ratings and risks destruction during surge events. Infineon specifies an external transformer-based or capacitive-dropper auxiliary supply with overvoltage clamping.
How is output over-voltage protection (OVP) triggered and reset?
OVP activates when VSENSE exceeds 5.25 V (corresponding to ~400 V bus with standard 1000:1 divider), forcing GATE shutdown. Recovery requires cycling VCC below 10.2 V (UVLO threshold) or pulling VSENSE below 0.8 V to reset protection latches - no automatic self-recovery.
